The maximum vertical distance between the line y = 10x + 39 and the parabola y = x^2 for -3 ≤ x ≤ 3 is 160 units.
To find the maximum vertical distance between the line y = 10x + 39 and the parabola y = x^2 for -3 ≤ x ≤ 3, we need to determine the points on the parabola that have the maximum vertical distance from the line.
Let's start by finding the points of intersection between the line and the parabola. Setting the equations equal to each other, we have:
10x + 39 = x^2
Rearranging the equation, we get:
x^2 - 10x - 39 = 0
Solving this quadratic equation, we find that x = -3 and x = 13 are the x-coordinates of the points of intersection.
Now, let's calculate the corresponding y-values for these x-coordinates on the parabola:
For x = -3, y = (-3)^2 = 9
For x = 13, y = (13)^2 = 169
Next, we can calculate the y-values for the line at these x-coordinates:
For x = -3, y = 10(-3) + 39 = 9
For x = 13, y = 10(13) + 39 = 169
Since the y-values of the line and the parabola are the same at the points of intersection, the maximum vertical distance occurs at the point (-3, 9) and (13, 169).
The maximum vertical distance between the line and the parabola is the difference in y-coordinates at these points:
169 - 9 = 160

Which one of the following statements is true? A. If 4 3 h = 12 , then h = 16 . B. If − 2 5 r = − 20 , then r = − 50 . C. If 1 2 = − 3 7 q , then q = − 1 1 6 . D. If 3 8 = 24 c , then c = 9 .
The only True statement is B: If −2/5r = −20, then r = −50
We can solve each equation to determine which statement is true.
A. If 4/3h = 12, then h = 16.
To solve for h, we can multiply both sides of the equation by 3/4:
4/3h * 3/4 = 12 * 3/4
h = 9
Therefore, statement A is false.
B. If −2/5r = −20, then r = −50.
To solve for r, we can multiply both sides of the equation by -5/2:
-2/5r * -5/2 = -20 * -5/2
r = 50
Therefore, statement B is true.
C. If 1/2 = −3/7q, then q = −116.
To solve for q, we can multiply both sides of the equation by -7/3:
1/2 * -7/3 = -3/7q * -7/3
q = 21/3 = 7
Therefore, statement C is false.
D. If 3/8 = 24c, then c = 9.
To solve for c, we can divide both sides of the equation by 24 * 8/3:
3/8 * 3/24 * 8/3 = 24c * 3/24 * 8/3
c = 1/3 * 8
c = 8/3
Therefore, statement D is false.
Therefore, the only true statement is B: If −2/5r = −20, then r = −50.

Alice drops a rock off a building that is 64 feet tall. If the equation for height as a function of time is: y = -16+2 + 400 where t is time in seconds and y is height in feet, how many seconds will it take for the drone to hit the ground? Now, set the equation equal to zero and solve.
By using Algebraic methods It will take 5 seconds for the rock to hit the ground when dropped from a building that is 64 feet tall, given the equation y = -16t^2 + 400.
The equation is y = -16t^2 + 400, where y represents the height of the rock in feet and t represents the time in seconds.
To find out how many seconds it will take for the rock to hit the ground, we need to set the equation equal to zero because the ground is at a height of zero.
0 = -16t^2 + 400
Now, we can solve for t using Algebraic methods.
First, we can subtract 400 from both sides of the equation:
-400 = -16t^2
Next, we can divide both sides by -16:
25 = t^2
Finally, we can take the square root of both sides:
t = ±5
Since we can't have negative time, we know that it will take 5 seconds for the rock to hit the ground.
So, to summarize, it will take 5 seconds for the rock to hit the ground when dropped from a building that is 64 feet tall, given the equation y = -16t^2 + 400.

To find the number of vinyl tiles needed to tile a kitchen measuring 24 ft. by 18 ft. with tiles measuring 8 in. each side, we need to convert all measurements to the same units.
First, we need to convert the kitchen measurements from feet to inches:
- 24 ft. = 24 x 12 = 288 in.
- 18 ft. = 18 x 12 = 216 in.
Next, we need to divide the length and width of the kitchen by the length of each tile to find the number of tiles needed in each direction:
- Length: 288 in. ÷ 8 in. = 36 tiles
- Width: 216 in. ÷ 8 in. = 27 tiles
Finally, we multiply the number of tiles needed in each direction to find the total number of tiles needed:
- Total tiles: 36 tiles x 27 tiles = 972 tiles

Find the volume of the triangular prism with a height of 2.8, width of 4.2, and a length of 8.
Answer:
Step-by-step explanation:
The formula for this is:
V = (1/2) x b x h x l
b= base
h=height
l=length
V= (1/2) x 4.2 x 2.8 x 8
so...I think the volume could be 47.04m^3?
PRO TIP: If you want to solve anything with volume, just write down every single formula they have for volume or area. It is good to memorize formulas like that.
The volume of the triangular prism with a height of 2.8, width of 4.2, and a length of 8 is 46.96 cubic unit.
The base area of the triangular cross-section must be multiplied by the prism's height to determine its volume. The triangle cross-section in this instance has a base of 4.2 and a height of 8.
The following is the formula to determine a triangle's area:
(Base * Height) / 2 = Area
When the values are plugged in, we get:
Base = 4.2
Size = 8
Area = (4.2 * 8) / 2 = 33.6 / 2 = 16.8
Next, increase the prism's base area by its height:
Volume = Base Area * Height = 16.8*2.8 = 46.96
The triangular prism therefore has a 46.96 cubic unit volume.

To find the lower quartile of a set of numbers, we need to determine the value that separates the lowest 25% of the data from the rest. In the given set of numbers, the lower quartile can be found by arranging the data in ascending order and identifying the value at the 25th percentile.
First, let's arrange the data in ascending order: 1 5 6 6 7 7 8 8 8 8 9 9 18 20 20 20 20 20 24 32 50 50 68 100.
To find the lower quartile, we need to determine the position of the 25th percentile. Since there are 23 data points, the 25th percentile corresponds to the value at the (25/100) * 23 = 5.75th position.
Since the position is not a whole number, we need to find the value between the fifth and sixth data points. The fifth data point is 7, and the sixth data point is also 7. Therefore, the lower quartile is 7.
The lower quartile represents the value below which 25% of the data lies. In this case, 25% of the data points are less than or equal to 7. It indicates that a quarter of the values in the dataset are smaller than or equal to 7, while the remaining 75% are larger.

find the length of the curve y=ln(cosx) from 0 to pi/3
To find the length of the curve y = ln(cos(x)) from 0 to π/3, we can use the arc length formula for a curve defined by a function y = f(x):
L = ∫[a to b] √(1 + (f'(x))²) dx.
In this case, the function is y = ln(cos(x)). Let's first find the derivative:
y' = d/dx ln(cos(x)).
Using the chain rule, we have:
y' = -tan(x).
Now we can calculate the arc length:
L = ∫[0 to π/3] √(1 + (-tan(x))²) dx.
Simplifying the integrand, we have:
L = ∫[0 to π/3] √(1 + tan²(x)) dx.
Using the trigonometric identity tan²(x) + 1 = sec²(x), we can rewrite the integrand as:
L = ∫[0 to π/3] √(sec²(x)) dx.
Taking the square root of sec²(x), we have:
L = ∫[0 to π/3] sec(x) dx.
Integrating sec(x), we get:
L = ln|sec(x) + tan(x)| [0 to π/3].
Evaluating the integral at the upper and lower limits, we have:
L = ln|sec(π/3) + tan(π/3)| - ln|sec(0) + tan(0)|.
Simplifying further, we have:
L = ln|2 + √3| - ln|1 + 0|.
Since ln|1| = 0, the second term on the right-hand side becomes 0, and we are left with:
L = ln|2 + √3|.
Therefore, the length of the curve y = ln(cos(x)) from 0 to π/3 is ln|2 + √3|.

The value of the constants a and b is 2 and -32 respectively.
The complete factorization of the polynomial is (x - 3)(x + 5) (2x - 1).
What are the values of the constants?The value of the constants is calculated as follows;
P(r) = ax³ + 3x² + bx + 15
If x - 1 is factor with a remainder of -12, then x = 1
P(1) = a1³ + 3(1²) + b(1) + 15 = -12
a + 3 + b + 15 = -12
a + b = -30
b = -30 - a
also, if x - 2 is a factor with a remainder of -21, then x = 2;
P(2) = a(2)³ + 3(2²) + b(2) + 15 = -21
8a + 12 + 2b + 15 = -21
8a + 2b = -48
4a + b = - 24
Substitute the value of b into the equation;
4a - 30 - a = - 24
3a = 6
a = 2
b = -30 - a
b = -30 - 2
b = -32
The quadratic equation will become;
P(r) = 2x³ + 3x² -32x + 15
We will factorize the equation as follows;
x - 3 is a factor;
2x² + 9x - 5
----------------------------------
x - 3 √ (2x³ + 3x² -32x + 15)
- (2x³ - 6x²)

We will factorize 2x² + 9x - 5
= 2x² - x + 10x - 5
= x(2x - 1) + 5(2x - 1)
= (x + 5)(2x - 1)
The complete factor = (x - 3)(x + 5) (2x - 1)

Function g can be thought of as a translated (shifted) version of f(x)=x^2
write the equation of g(x)
The equation of the red graph, g(x) is g(x) = (x + 3)² - 4
How to calculate the equation of the red graphFrom the question, we have the following parameters that can be used in our computation:
The functions f(x) and g(x)
In the graph, we can see that
The blue graph passes through the vertex (0, 0)The red graph passes through the vertex (-3, -4)This means that
g(x) = f(x + 3) - 4
Recall that
f(x) = x²
This means that
g(x) = (x + 3)² - 4
This means that the equation of the red graph is g(x) = (x + 3)² - 4
